Fregattenkapitän Heinrich Lehmann-Willenbrock (11 December 1911 – 18 April 1986) was a submarine commander in the Kriegsmarine of Nazi Germany during World War II. He commanded four U-boats, including U-96, a Type VIIC U-boat, which gained widespread recognition when one of its patrols was documented and publicized by an accompanying member of a propaganda company Lothar-Günther Buchheim. Lehmann-Willenbrock was awarded the Knight's Cross of the Iron Cross with Oak Leaves. The story of the U-96 was eventually made into a mini-series and film called Das Boot, in which the captain was portrayed by Jürgen Prochnow.
